Has anyone embedded a web-UI into a C++ project?
Here's what I did: - I bought a theme that I liked, and used mstch as template engine (matched the theme's template format) - Imported rapidjson for parsing JSON, and used mstch for generating JSON (the JSON I generate is simple enough that I can do this) - Wrote an HTTP handler class for each page that handles the GET and POST requests, generating HTML or JSON depending on the request

Is there a good cross-platform (Windows / Linux) C or C++ library for file I/O?
And documentation in most cases is more user-friendly if you will use something like MkDocs(based on Markdown), example http://rapidjson.org/

DAW JSON Link v3, a JSON serialization/deserialization library, is released
It seems not super widely used compared to other famous libraries like RapidJSON, nlohmann-json, or simdjson. But it seems the author is very active in developing this project which can mitigate this "lack of community" issue.

Is cpp a good language for reading and writing large quantities of JSON files as quickly as possible?
have a look at rapidjson for a a nice simple json framework https://rapidjson.org/ I use it and it's quite fast and as good as anything I used in python.
-
What JSON library do you suggest?
So I just cloned https://github.com/Tencent/rapidjson to see what is the current status. At compile time they check if the C++ compiler supports the "noexcept" keyword, and if so they define RAPIDJSON_NOEXCEPT to be "noexcept". Throughout the implementation, RAPIDJSON_NOEXCEPT is added to quite a few function declarations (about a hundred of them).
- Storing data to be used in simulations.

How and where I can learn about Web sockets, APIs, Wrappers to connect with my C++ code?
RapidJSON is also excellent, like fantastic when performance matters. Not sure there's a much faster JSON implementation anywhere, and I've written my own SAX-style parser as a fun, hobby project for C++.
- Can anyone point me to an open-source project that correctly uses allocators?

Has Boost lost its charm?
They might have good luck with https://github.com/beached/daw_json_link it has support for stuff like JSON lines and alike plus other ways that only use as much ram as their underlying data structures do as it parses directly to the user DS. Plus it has an iterator/range interface for things like arrays if needed.

New, fastest JSON library for C++20
We will add more benchmarks in the future, but for now you can see the comparison of daw_json_link with rapidjson. glaze is faster than daw_json_link, which is over twice as fast as rapidjson.

What are some cool modern libraries you enjoy using?
I am biased, but prefer https://github.com/beached/daw_json_link Super fast and you work with your native data structures without the overhead of DOM parsing/lookup

How to deserialise json into a C++ struct?
You can also look into https://github.com/beached/daw_json_link which claims to support nullable values in the readme.

JSON for Modern C++ 3.11.0
The library I author does this. https://github.com/beached/daw_json_link . It's fast, GB/s too, and provides the mapping mechanism, iteration types, json lines support, event based parser, along with a non-owning json_value for when the mappings don't fit right or if one is querying. Pretty much everything but an owning JSON value as it's not something I've ever needed more than temporarily and brings a lot of complexity that is solved by using the actual C++ data structures one is eventually parsing into anyways.
-
DAW JSON Link v3, a JSON serialization/deserialization library, is released
So DAW JSON Link does have a DOM view, however it does not have a owning view. The json_value(even supports JSON Path in a limited form) type and json_raw mappings can help here. But there is no hard line between parsing view the json_value and the mappings to concrete data structures. One can mix and match.
